HEF4519BP datasheet


Description :

The HEF4519B provides four multiplexing circuits with common select inputs (SA, SB); each circuit contains two inputs (An, Bn) and one output (On). It may be used to select four bits of information from one of two sources. The HEF4519B cannot be used to multiplex analogue signals. The outputs utilize standard buffers for best performance.

74HC258N datasheet

Description :

The 74HC258N / 74HCT258 are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

The 74HC/HCT258 have four identical 2-input multiplexers with 3-state outputs, which select 4 bits of data from two sources and are controlled by a common data select input (S). The data inputs from source 0 (1I0 to 4I0) are selected when input S is LOW and the data inputs from source 1(1I1 to 4I1) are selected when S is HIGH.


1. Inverting data path
2. 3-state outputs interface directly with system bus
3. Output capability: bus driver
4. ICC category: MSI.
